什么是gateway

gateway资源详解_redis_02

在Kubernetes环境中，Kubernetes Ingress用于配置需要在集群外部公开的服务。但是在Istio服务网格中，更好的方法是使用新的配置模型，即Istio Gateway。Gateway允许将Istio流量管理的功能应用于进入集群的流量。

gateway 分为两种，分别是ingress-gateway和egress-gateway，分别用来处理入口流量和出口流量。gateway本质也是一个envoy pod。

mode

Name	Description
PASSTHROUGH	客户端提供的SNI字符串将用作VirtualService TLS路由中的匹配条件，以根据服务注册表确定目标服务
SIMPLE	使用标准TLS语义的安全连接
MUTUAL	通过提供服务器证书进行身份验证，使用双边TLS来保护与下游的连接
AUTO_PASSTHROUGH	与直通模式相似，不同之处在于具有此TLS模式的服务器不需要关联的VirtualService即可从SNI值映射到注册表中的服务。目标详细信息（例如服务/子集/端口）被编码在SNI值中。代理将转发到SNI值指定的上游（Envoy）群集（一组端点）。
ISTIO_MUTUAL	通过提供用于身份验证的服务器证书，使用相互TLS使用来自下游的安全连接
